Discussion:
do_IRQ: 0.165 No irq handler for vector (irq -1)
(too old to reply)

I'm still trying to get the MSI support for sata_sil24, that was added
in 2.6.33-rc1, to work. But even with -rc6 it still shows the same
errors.

The current best guess is, that there is something fishy going on in
the IRQ system, as the only error messages before the libata timeouts
start are:

[ 86.463814] do_IRQ: 0.165 No irq handler for vector (irq -1)
[ 86.463832] do_IRQ: 3.165 No irq handler for vector (irq -1)
[ 86.463848] do_IRQ: 1.165 No irq handler for vector (irq -1)
[ 86.463867] do_IRQ: 2.165 No irq handler for vector (irq -1)

(Thats why I added CCs for get_maintainer.pl -f arch/x86/kernel/apic/io_apic.c)

To get these errors I only boot with sata_sil24.msi=1 and then do: dd
if=1GB-file-on-ro-mounted-xfs-fs of=/dev/null bs=1k

Writing with enabled MSI also fails with timeouts, but in this case
there is no error from do_IRQ.

What is really strange: The vector 165 is stable. It never changed
even if I deactivate all other drivers in the kernel config (that
changes the MSI IRQ for sata_sil24 from 29 to 28!) or if I switch off
CONFIG_SPARSE_IRQ. In the kernel with the reduced number of drivers
the maximum vector that gets used in __assign_irq_vector is only 137.

Both Robert Hancock and Tejun Heo provided different patches for
sata_sil24 to access a additional MSI register on the SiI-chip, but
neither change the behavior of my system.

I also do not think that MSI is completely broken, as the drivers
radeon (X300), HDA Intel (onboard sound from NVidia MCP55) and tg3 (2x
BCM5754) work fine with MSIs.

After the test and the do_IRQ-errors the important changes are:
29: 0 0 0 2023 PCI-MSI-edge sata_sil24
-> Some interrupts where delivered. I am able to mount the xfs
filesystem and dd says it could read the first 180 MB successfull.
ERR: 15
-> I have no clue how 8 do_IRQ errors translate to an increase of 14...

If you need more information or have a patch I should test, just ask.
At the end of the mail is the complete dmesg from the testrun with
-rc6. I also added apic=debug to the commandline, but did not see
anything related to this strange irq vector 165.

Hello, Torsten.
Post by Torsten Kaiser
I'm still trying to get the MSI support for sata_sil24, that was added
in 2.6.33-rc1, to work. But even with -rc6 it still shows the same
errors.
The current best guess is, that there is something fishy going on in
the IRQ system, as the only error messages before the libata timeouts
[ 86.463814] do_IRQ: 0.165 No irq handler for vector (irq -1)
[ 86.463832] do_IRQ: 3.165 No irq handler for vector (irq -1)
[ 86.463848] do_IRQ: 1.165 No irq handler for vector (irq -1)
[ 86.463867] do_IRQ: 2.165 No irq handler for vector (irq -1)
(Thats why I added CCs for get_maintainer.pl -f arch/x86/kernel/apic/io_apic.c)
To get these errors I only boot with sata_sil24.msi=1 and then do: dd
if=1GB-file-on-ro-mounted-xfs-fs of=/dev/null bs=1k
Writing with enabled MSI also fails with timeouts, but in this case
there is no error from do_IRQ.
It might be that the silicon implements MSI incorrectly and ends up
sending out invalid MSI packets under certain circumstances. The
silicon hasn't changed for quite some time now and back when it came
out MSI wasn't too popular and I don't think SIMG's proprietary
drivers use it, so it's quite possible that the feature simply is
broken. Is there any specific reason why you want to enable MSI
support? It's not like MSI brings any actual benefit when the
compatibility hardware is already there.

Thanks.

Fascinating I think get_maintainer.pl missed the maintainers.

sending out invalid MSI packets under certain circumstances. The
silicon hasn't changed for quite some time now and back when it came
out MSI wasn't too popular and I don't think SIMG's proprietary
drivers use it, so it's quite possible that the feature simply is
broken. Is there any specific reason why you want to enable MSI
support? It's not like MSI brings any actual benefit when the
compatibility hardware is already there.
It also seems possible that some of the recent irq handling changes
missed something.

Usually the message "No irq handler for vector (irq -1)" means that the irq
was delivered to a cpu that was not ready for it. I see that vector 165
is being delivered on all of the different cpus with vector 165,
and that you are getting interrupts delivered most of the time.

This smells like the initialization problems I was seeing in another
thread. Suresh?

No Eric. This particular report is with 2.6.33-rc kernels and also only
when MSI support for sata_sil24 is enabled. Recent irq handling changes
are all in -tip tree and getting tested. So this sounds like a different
problem specific to this HW's MSI capabilities.

What is really strange: The vector 165 is stable. It never changed
even if I deactivate all other drivers in the kernel config (that
changes the MSI IRQ for sata_sil24 from 29 to 28!) or if I switch off
CONFIG_SPARSE_IRQ. In the kernel with the reduced number of drivers
the maximum vector that gets used in __assign_irq_vector is only 137.
It looks like the HW under certain conditions is generating interrupts
with wrong vector (165), especially when the __assign_irq_vector() never
allocated the vector 165 (and hence we never setup the vector to irq
mapping for this vector on any cpu). Torsten, can you please apply the
appended patch and boot with "apic_phys" boot parameter and see if it
makes any difference?

No. Initialization problems in another thread happens in a small window
during cpu online (in logical flat mode, we are setting up vector to irq
mappings for the AP a little late after we have enabled interrupts).
Here the problem is not actually triggered during cpu on-lining.

Thanks.

I tried the patch and the message from do_IRQ is gone, but reading the

(Earlier tests with writing a large file to this disk also failed with
timeouts, but never trigger the do_IRQ error)

I added a diff between the dmesg from the testrun with your patch to

Ping?

I reported this problem one day after -rc1 was out and it's still
there in -rc8, the probably last -rc for 2.6.33.
(I also reported it against -rc2, -rc3, -rc4 and -rc6)

Apart from the patches related to the SiI register HOST_CTRL_MSIACK
(that did not fix the problem) I have the feeling, that I'm not one
step further to any fix.

Is this a bug in the MSI-enable code in sata_sil24?
Is this a bug in the MSI code in libata?
Is this a bug in the IRQ system?
Is this a bug in the x86 apic code?

Is this a hardware bug in the SiI 3132?
Is this a hardware bug in the MCP55?
Is this a fatal bug or does it just need the right quirk?

What should I do now?
Keep posting that it's still broken at each -rc?
Open a bug at bugzilla.kernel.org? Against what subsytem?
Should I just not use the sata_sil.msi=3D1 commandline? Or should
dae77214fa71898b84514e43721fb7bf260b026a be reverted?

Ping?
I reported this problem one day after -rc1 was out and it's still
there in -rc8, the probably last -rc for 2.6.33.
(I also reported it against -rc2, -rc3, -rc4 and -rc6)
Apart from the patches related to the SiI register HOST_CTRL_MSIACK
(that did not fix the problem) I have the feeling, that I'm not one
step further to any fix.
Is this a bug in the MSI-enable code in sata_sil24?
Is this a bug in the MSI code in libata?
Is this a bug in the IRQ system?
Is this a bug in the x86 apic code?
There are primarily two issues you reported.

One is the spurious interrupt issue (for which you see "no irq handler
for vector messages). From your experimental results you verified that
this problem doesn't happen in physical apic mode. This shows that there
is some problem with the way this HW subsystem (involving sata_sil24)
handles logical mode. Most likely some bug either in the sata_sil24 or
in the platform paths (bridges etc) handling the sata_sil24 interrupts
(as you say, other devices work fine with MSI on this platform).

And the second problem is the sata timeouts (which happen irrespective
of the above spurious interrupts). It looks like interrupts are dropped
(which might be the reason why your ERR count -- apic error count --
increases).

Based on your experimental results, we can say that it is not the bug
with x86 apic code and irq subsystem.

Is this a hardware bug in the SiI 3132?
Is this a hardware bug in the MCP55?
Is this a fatal bug or does it just need the right quirk?
What should I do now?
Keep posting that it's still broken at each -rc?
Open a bug at bugzilla.kernel.org? Against what subsytem?
Should I just not use the sata_sil.msi=1 commandline?
You should n't use that command line as your experiments showed that
sata_sil msi mode is clearly broken on this platform and perhaps report
the issue to the HW vendor (you should include in that report, the
spurious vector 165 that you see in logical mode and also the apic error
you see -- you can enable debug to see the error message that gets
printed in smp_error_interrupt() for this --)

Since the MCP55 onboard controller also fails, this seems rather like
a chipset problem. Maybe some of the PCI-E links spuriously fail MSI
sometimes? Does anyone have any good chipset contacts at NVIDIA these
days? Peer Chen was CCed on the Bugzilla report, but didn't respond.

Yes, I understand that this message is more a symptom then the cause.
But it was the only error message I had, as the sata timeouts also
look more like symptoms from a missing interrupt then a real error in
the ATA request or response.
So I hoped that with this error and the vector number 165 that was
strangely constant it would be possible to trace this to what causes
the interrrupts to go missing or misrouted.

(which might be the reason why your ERR count -- apic error count --

But as I never hat and error about the dropped interrupts, I didn't
have anything to look for further clues.

Thanks to your hint about smp_error_interrupt, I redid the read- and
write-tests with 2.6.33-rc8 and got these additional messages:

chipset)

If I'm reading the comment in smp_error_interrupt right, this would
mean there is a "Receive accept error" in the APIC.
But only after each CPU gets two! errors from do_IRQ the flag for
"Received illegal vector" gets triggered?

Something strange in the irq-cpu-affinity?
(The test installation where I ran these tests does not have
irqbalance installed...)

Based on your experimental results, we can say that it is not the bug
with x86 apic code and irq subsystem.
For my experiments I only see that sata_sil24 and sata_nv sometimes
lose interrupts in MSI mode, while tg3, hda-intel and radeon do not.
But I don't see a real pattern to pinpoint a cause.

Both the tg3's and the sata_sil24 are onboard chips that are connected
to PCIe links from the MCP55.
Both the onboard audio (driven by hda-intel) and the sata_nv-ports are
part of the chipset itself.
That would suggest that neither the PCIe bridge nor the chipset itself
is to blame.
And as the system without MSI is perfectly stable, I also can't blame
the cableling or the hard drives.

But when I looked into the code from tg3,radeon and sata_sil24 about
the MSI enables I also did not see any fundamental differences. All
just seemed to call pci_enable_msi()...
That would point in the direction of the common code: libata or irq system.
And as I can't see anything MSI related in the libata core, my prime
suspect is this still something weird with the irq system.

I'm willing to investigate this further, but I lack the needed
background information about how innards of the IO-APIC and the other
involved parts work...

OK, the easy "solution" for me would be to just ignore this new MSI
support for sata_sil24.
But should the kernel have a commandline option
"randomly_disconnect_harddrives_and_lose_unwritten_data"?
